I MANUFACTURE OF WIRE-BOUND RECEPTACLES.

Specification of Letters Patent.

Patented Sept. 29, 1914..

Application filed November 22, 1912. Serial No. 782,997.

' T all whom it m (13 concern Be it known that I, Join" SHELLEXBER GER, a citizen of the ['nited States, residing at Rome. in the county of Floyd and State of Georgia, have invented certain new and useful Improvements in and Relating to the Manufacture of Fire-Bound Receptacles, of which the following is a specification.

This invention relates-to certain improvements in wire bound receptacles or boxes; and the objects and nature-of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating what I now believe to be the preferred embodiment from among other formations, arrangements, constructions and means within the spirit and scope of my invention.

The invention consists in certain novel fea-. tures in construction and in combinations and formations as more fully and particularly set forth hereinafter.

- Referring to the accompanying drawings:

Figure 1, is a perspective view of the box blank or web as it appears at a certain stage in the method of producing wire bound receptacle webs or blanks. Fig. 2, is a perspective view of the finished or complete blank or web. Fig. 3. is a perspective view of a box or receptacle built from said blank. Fig. 1, shows a detail on an enlarged scale, of the blank of Fig. 2. Fig. 5, is a perspective view. corresponding to Fig. 1, but showing a difierent construction of web or blank before completion. Fig. 6. is a perspective view of the blank of Fig. 5, when completed. Fig. 7, is a detail, on an enlarged scale, of said blank of Fig. 6. Fig. 8. is a perspective of a box or receptacle built from the blank of Fig. 6. Fig. 9 is a detail, on an enlarged scale. of the receptacle of Fig. 8.

Wire bound boxes or receptacles are usually composed of continuous webs or blanks, each bent to form the bottom, sides and top of a receptacle. suitable headings being provided to form the receptacle or box ends. These webs are produced flat or continuous, from longitudinal strips and cross or wall forming sheets. such as boards or veneers, traversed by wires and secured together by the staples securing the wires. In making the blanks. the wall forming sheets and longitudinal pieces have usually been assembled in suitable forms and fed or carried through stapling machinery whereby the wire binding and securing staples were applied. Each blank or web embodied a section to form the box bottom, sections accurately spaced from said bot-tom section to form the box sides, and a section accurately spaced from a side to form the box top. These sections were united and held spaced by the wire bindings and sometimes by battens. hen the blank was folded to form the box, the bottom and top sections overlapped or extended across the longitudinal edges of the side sections in an effort to form perfect or tight corners. Each wall section of a blank was usually composed of several parallel boards or veneer sheets of various widths. These sheets were usually composed of thin rotary cut lumber 0r veneer which is subject to excessive shrinkage, and warpage. The sheets also varied in width.

It has been-necessary to carefully size sheets foreach blank section, inorder to produce each section of the accurate width required- It has been also necessary to provide accurate forms or spacing devices to maintain the sheets forming the separate sections, properly spaced apart, while being fed to and operated on by the stapling and wire binding applying mechanism. It was also necessary to exercise great-care in placing the sheets in such forms or on the conveying devices leading to the stapling machine. Often the sheets are cupped or warped when picked out and sized and hence the width thereof will be unduly increased when flattened out by the application of the wire binding and in some instances the sections will be too narrow. These methods heretofore followed, have been expensive and have resulted in the production of a large percentage of culls and imperfect boxes particularly in the manufacture of high grade or tight wire bound veneer packing cases and the like.

According to the preferred method of producing the article of this invention, separate wall formin sections are not taken into consideration 1n assembling the boards or veneers to form a web or blank, inasmuch as I assemble a sufiicient number of boards or sheets to approximate a web of words, comprises a plurality of flat parallel closely arranged abutting sheets, and is not forming sections. These grooves extend partially through the tight web and are of such formation that when the web is folded the box formed thereby will be provided with miter joints between its wall sections forming approximately tight angles or longitudinal corners.

In forming the web of Fig. 2, for instance, I will assemble a series of flat horizontal thin sheets 1, and arrange them with their longitudinal edges abutting. Each sheet can be of any width and any number of sheets can be employed so that the aggregate widths thereof will approximately equal the length of the web to be produced. Several battens 2, are arranged across these sheets, usually, across the ends and intermediate portions thereof, and wires 3, are arranged longitudinally of the outer faces of the battens. The sheets, battens and wires are rigidly secured together by staples fl,

straddling the wires and extendin through the battens and sheets and clinc ed. The stapled wire bindings are usually applied by a suitable stapling machine, and I usually provide this machine with a conveyer or other feeding means on which the sheets are carried to the stapling mechanism. The sheets can be quickly and easily placed on such conveyer as sizing and spacing of the sheets are not required.

The tight close web, Fig. 1, is then provided with transverse parallel cuts extending completely across the same and partially therethrough along the lines on which the web is to be folded in forming the box walls. In the example illustrated, threeasuch cuts are provided forming the fold lines.- between the bottomand sides and between a side and the top.

I prefer to provide a suitable wood work- I ing machine, having a gang of saws or other cutters arranged to simultaneously and -accurately form the desired number of properly spaced'cuts or grooves across thenweb,

when-the web is fed into the machine... I

; also preferably provide this machine with trimming saws to -trimeither or both ends ofthe 'webto accurately reduce thesame to the length. desired at -the same time that the cuts or. grooves are formed.

vEachcut-is in the form of a V-groove extendingcompletely through the sheets and partially but not completely thr0uglrthe battens. The cuts thus divide the sheets into wall sections having their longitudinal edges 7, beveled from their inner faces to their outer faces. The edges 7 of adjoining sections are parallel and spaced a distance apart. The cuts extend into the battens and form V-grooves 8, therein transversely across the inner faces thereof. The faces 7 8, of each miter-groove out are arranged at such an angle that when the web is folded into box form the cuts or grooves will close together and said faces will abut to form approximately tight miter joints 9, at the corners of the box and throughout the length thereof. The wall sections will be held together by the battens and wire bindings and most accurate, tight and durable corner joints will be provided. When rectangular boxes are to be formed with the wall sections arranged at right angles to each other, the grooves or cuts are formed to provide the faces 7 and 8, at angles slightly less than 45, whereby when the web is folded into box form said faces 7, 8, will be tightly pressed together and the wood at such faces will be to a certain extent compressed and thus held by the wire bindings. Strong tight corners will be thus produced and slight shrinkage can occur without causing such compressed joints to open.

Any suitable mechanism can be provided to cut the miter or V-grooves across the web and-accurately spaced with respect to each other, and'the web ends. These mechanisms can be provided with adjustable cutters to operate on and produce accurate correct webs of any desired length for the formation of boxes of different sizes.

If so desired the ends of the web can be sawed or otherwise cut squarely off, so that the free end of the cover or top will extend across and close down on the top edge of the ad'acent side wall of the box, as illustrated y Fig. 3.

My method can also be ractised in the production of webs having t e wall forming sheets secured to cleats adapted to abut when the web is folded into box form and constitute box end frames forming parts of panel end heads or frames. In the production of such webs, I arrange the wall forming sheets 1', closely together with their ends traversed by and resting on the top longitudinal edges and secured by staples4.:The staples strad I dlingthe wires on the ends -ofthe sheets 1',-

extend-into the strips-2', and thereby secure -the sheet-s to said strips as well as-said -wires tothesheets. The binding wires and staples can be appliedgby a suitable stapling ma-; chineas hereinbefore described... I show this 4 web as so far described, in Fi 5. The-web of. Fig. 5, is then run orfedtlii'o ugh a suit- -of strips or cleats; ,2], extendingthe. full; length of theweb. Iprovide, binding. wires 3, traversing-the top faces of the sheets 1 able grooving machine, such as hereinbefore described, to cut miter or V-grooves thereacross to form the fold lines and subdivide the web into wall sections. The web of Fig. 5 5, is run through the grooving machine with the strips 2', next to the grooving cutters, whereas the web of Fig. 1, is placed in the grooving machine with the side having the battens away from the cutters. The V-grooves completely sever each strip 2, into separated cleats and extend into the sheets 1'.

I 'refer to employ cutters to form combined step-miter and straight miter V- grooves, in the web of Fig. 5. The step miter faces 10, extend partially across the inclined ends of the cleats 2', and the straight V-miter faces 11, extend across the maintaining portions of said edges of said ends in continuation of the inclined side faces of the V-grooves 12, through or almost through, the sheets 1. The angles of the beveled side walls of these grooves are also preferably slightly less than 45 degrees to cause compression of the wood at said faces when the web isfolded into and secured in box form.

Fig. 6, shows the completed web having the inner side cleats. When this web is folded into box form, the cleats are arranged in the box ends to form the frames of panel ends receiving panels 13. The ends of the cleats tightly abut to form step miter joints 14, and straight bevel or miter joints 15, while the sheets form closed straight bevel miter joints 16, tightly held'by the outside wire bindings. These oints form closed corners throughout the length of the box.

I use the term wire herein in a board sense to include any equivalent binding con nection.

I do not wish to limit all the features of my invention to the use of the battens of Fig. 1, nor to the use of the cleat forming strips of Fig. 5.

In stapling the wall sheets, battens (or strips) and binding wires together the staples can be so located or spaced in the web that the grooving. cutters-or saws can 50 cut the V-grooves without striln'ng staples.

Various changes and modifications might be resorted to without departing from the spirit and scope of my invention as defined by the following claims and hence I do not 55 wish to limit myself to the exact disclosures hereof. i

Desiring to protect my invention in the broadest manner legally possible, what I claim is 1. A wire bound receptacle comprising closely assembled longitudinal wall-forming sheets, battens and wire bindings traversing the outer surfaces of said sheets and securing them together and continuous across the 55 longitudinal corners of the receptacle, the

longitudinal edges of sheets at the corners of the receptacle being parallel and beveled throughout their lengths and tightly compressed together to form closed miter joints extending throughout the length of the receptacle.

2. A wire bound flat web adapted to be folded to form walls of a wire bound receptacle, said web embodying wall-forming sec- .tions and intervening V-cuts constituting closely assembled wall forming sheets, battens and wire bindings traversing the outer surfaces of said sheets and securing them together, said web having V-cuts extending transversely across the same at the fold lines and through the sheets and forming V- grooves across the battens, said cuts dividing said sheets into wall forming sections having spaced longitudinal adjacent beveled edges at the inner side of the web with said grooves in the battens centrally arranged between adjacent edges, said edges adapted to meet and squarely abut under compression throughout their lengths when the web is folded into box form and thereby form the box with tight corner bevel-miter-joints throughout its length.

4. A wire-bound flat box-web consisting of a plurality of parallel boards fitted snugly together with their longitudinal edges engaging and wire bindings stapledv to and traversing all of said boards and securing the same together and continuous across the joints between the boards, said web formed with V-cuts extending transversely across the same at the fold lines and forming-wall sections having spaced longitudinal adjacent beveled edges at the inner side of the web and adapted to meet and squarely abut under compression throughout their lengths when the web is folded into box form and thereby form compressed corner bevel-jointsthroughout the length of the box, said cuts extending longitudinally of and approximately through said boards without regard to the meeting edges of said boards.

3 5. A wire-bound flat box-web adapted to be folded to form walls of a wire bound receptacle, said Web consisting of wall forming sections and exterior wire bound battens traversing said sections, securing them together and bridging the joints therebetween,

said web formed with V-ciits constituting the fold lines between the sections and separating the sections and forming V-grooves across the inner faces of the battens, the longitudinal edges of said sections forming I the spaced walls of said cuts and being parallel andbeveled completely across the web,

- the walls of each cut converging at an angle slightly less than the angle formed by the across the longitudinal corners of the I'BCGP".

tacle, the longitudinal edges of sheets at the corners of the receptacle being "beveled throughout their lengths and tightly compressed together to form closed miter joints extending-throughout the length of the receptacle, said battens having cuts in continuation of said beveled edges with the walls thereof compressed together at and in continuation of said joints.

7. A wire bound receptacle consisting of a flat web having exterior wire bindings, said web being folded to form the walls of the receptacle, said receptacle having end heads to which said web is secured, said web embodying a plurality of narrow parallel boards fitting snugly together with their longitudinal edges engaging and traversed and secured together by the wire bindings, said bindings being stapled to all of said boards, the sheet formed by said boards being divided into wall forming sections having their longitudinal edges at the corners of the receptacle beveled throughout their lengths and tightly compressed together to form closed miter-joints extending throughout the length of the receptacle and bridged by said wire bindings.

In testimony whereof I afiix my signature in presence of two witnesses.
